iKnob anyone

Thanks to John for sending in this link to the iKnob!

• Lets you plug into your amp without having to search for those little adapters that you left at home!
• Lets you control the volume you need with a simple large volume knob.
• A lot easier than trying to balance on a volume pedal or twisting tiny knobs or sliders on your amp or mixer.
• Allows you to plug in your iPod or any audio output device using standard 3.5mm plugs or RCA plugs.
• Converts stereo to summed mono to get the right signal to your amp.
• Has channel cut-off switches so you don’t have to prepare “music minus one” audio files at home — just flick a switch and the soloist is eliminated!
• Requires no power source.
